Mercedes A-Class review

Introduction

Sequels are rarely better than the original, and when you string an idea out for a third or fourth instalment, it’s often a sign that it's past its sell-by date. On first inspection, it can seem that way with the Mercedes A-Class.

You see, the original A-Class was remarkably innovative, but its successors (particularly the third-generation model) were a lot less recommendable. So, logic might lead you to assume that this fourth-generation car is nothing special but, without wanting to give too much away, that's not the case at all. In fact, it’s really rather good.

AMG Line

If you can, we’d suggest stepping up to AMG Line Executive because it doesn’t cost all that much more but comes with larger 18in alloy wheels and the incredibly comfortable sports seats. Other than that, you’ll find lots of AMG styling upgrades across the exterior and interior.

Sport

This is the entry-level model, but still comes with plenty of standard equipment. The list includes 17in alloy wheels, climate control, heated front seats, LED headlights, wireless phone-charging, parking sensors all round and a reversing camera.

Performance & drive

What it's like to drive, and how quiet it is

Engine, 0-60mph and gearbox

If you're after diesel power for your Mercedes A-Class, the only engine choice is the A200d – and it’s a cracker. It’s nippy and earns its spurs with a progressive power delivery that’s spread evenly through the rev range, taking as little as 8.3 seconds to get to 62mph from a standstill.

What about petrol options? Well, the entry-level A180 needs to be worked quite hard to keep up with traffic.

The automatic gearbox does a pretty good job of keeping you in the right gear to maintain momentum, but the more powerful A200 is noticeably pokier, and is our pick of the engines. Officially, it’ll cover 0-62mph in 8.2 seconds – quicker than the Audi A3 35 TFSI and BMW 118i.

Want something even faster? You’ll need one of the hot hatch versions. For more on those see our reviews of the Mercedes-AMG A35 and Mercedes-AMG A45.

Suspension and ride comfort

The A-Class has a softer suspension setup than the A3 and 1 Series, making it one of the comfiest family cars over pockmarked town roads and sleeping policemen.

Despite that, for the most part, the ride is well controlled and it settles down nicely as speeds increase. True, there’s a touch more float and bounce along undulating country roads than you'd experience in its two key rivals, but not enough to prove a real problem.

If you really value a cosseting ride, the best car in the class is the VW Golf fitted with optional adaptive suspension.

Handling

The A-Class handles pretty well. There’s a bit of body lean through faster corners, but it happens so progressively that the car never feels unstable during quick changes of direction.

The steering impresses, too: it’s responsive, builds weight naturally and, combined with good accuracy, means you can place the car easily on the road. It’s also light enough to ensure town driving isn't a chore.

Even so, if you’re after something more fun that isn’t a hot hatch, the 1 Series is noticeably more agile on a country road and generally more entertaining to drive.

Noise and vibration

The 1.3-litre petrol engines in the A180 and A200 aren’t the most refined, but that's noticeable mainly when you work them hard. There’s some vibration through the steering wheel in the A180 at higher revs, while the A200 suffers from a noisier turbocharger hissing away. The engine in the BMW 118i is smoother and quieter, as is the one in the Audi A3 35 TFSI.

The A200d is relatively hushed for a diesel, although its eight-speed automatic gearbox can be a little jerky in traffic. Fortunately, the seven-speed auto that comes with the petrols is smoother.

There’s more wind noise at speed than in the A3 and 1 Series, but road noise is better tempered than in both those rivals, so overall the A-Class is slightly quieter at motorway speeds.

"Even in such a hotly contested class with so many excellent rivals, the A-Class stands out for its ride. It's surprisingly good to drive, too. From behind the wheel, I could easily imagine driving a much larger and more expensive Mercedes." – Neil Winn, Deputy Reviews Editor

Interior

The interior layout, fit and finish

Driving position and dashboard

You’re unlikely to have much difficulty getting comfortable behind the wheel of the Mercedes A-Class. The steering wheel has plenty of height and reach adjustment, and the driver’s seat, which adjusts manually on all trim levels, supports you in all the right places.

The sports seats in AMG Line models are our favourite for all-round comfort, with plenty of lower back support – although you might find that the integrated headrests push your head forward more than you'd like.

The most regularly used dashboard buttons are easy to operate, although the touch-sensitive controls on the steering wheel are very fiddly to operate. All models come with a crisp 10.3in digital driver's display behind the steering wheel, which is joined to another 10.3in infotainment screen in the centre of the dashboard.

Visibility, parking sensors and cameras

All-round visibility in the A-Class is pretty good. The windscreen pillars are relatively narrow, so you can see around them easily enough, so it's only over-the-shoulder vision that could be described as "iffy".

To help remove any guesswork when manoeuvring, all models come with a rear-view camera and all-round parking sensors as standard. The top-spec AMG Line Premium Plus trim gets a 360-degree camera instead.

All versions have LED headlights, with adaptive LED headlights (which can remain on main beams without dazzling other drivers) fitted to AMG Line Premium Plus.

Sat nav and infotainment

When it comes to infotainment tech the A-Class is right up there with the BMW 1 Series. All versions have a 10.3in touchscreen with Android Auto and Apple Carplay smartphone mirroring.

Using the touchscreen is fine if you're parked, but with a lot of swiping and sub-menus to get through, it can be distracting while driving. In theory, you can use touch-sensitive pads on the steering wheel to navigate around the infotainment system, but this is extremely fiddly. The rotary controller interface that features in the 1 Series is far more intuitive.

As in the 1 Series, you get a Siri-style personal assistant as standard. To wake it up, you say "Hey Mercedes" then, in theory, use normal speech to control various aspects of the car, from the sat-nav to interior temperature. It’s fun to use and mostly gets things right, but less so if someone else is talking in the car.

Quality

If there’s one thing the A-Class has nailed, it’s the visual appeal of its interior. It’s eye-catching and more in keeping with what you’d expect to find in a luxury car than a hatchback family hatchback, thanks to lashings of gloss-black plastic, faux leather and metal inserts.

Turbine-style air vents also lift the overall impression above most other premium-badged rivals, especially at night because they glow like afterburners.

Unfortunately, the build quality isn't as good as the looks might suggest. For example, the climate control panel flexes when you press a button, while the outer heater vent surrounds don't appear to be very well secured. Overall, the A3 and 1 Series feel better screwed together.

"I love the looks of this car on the exterior but the interior is a delight too. The driving position is quite low-slung and feels sporty, and I reckon thehe three turbine-style air vents that run along the dashboard look terrific." – Lawrence Cheung, New Cars Editor

Passenger & boot space

How it copes with people and clutter

Front space

You’re unlikely to grumble about space in the front of the Mercedes A-Class, even if you tower over most of your friends and colleagues. The seats slide back a long way and there’s plenty of head room, if not quite as much as in the BMW 1 Series.

It's worth bearing in mind that the panoramic sunroof (standard with the AMG Line Premium Plus trim) reduces head room by about 6cm, so is best avoided if you're really tall.

The door pockets are big enough for a couple of 500ml bottles and there are two suitably deep cupholders, as well as some storage under the large centre armrest.

Rear space

Anyone over six feet tall will be comfy enough in the back; they won’t exactly be sprawled out, but neither will they be packed in with knees tucked up under their chin.

Indeed, there’s roughly the same amount of rear-seat space as you’ll find in the rival A3, while the BMW 1 Series and VW Golf are a little bit bigger. If you can live without a premium badge, there are far roomier family cars including the Ford Focus, the Seat Leon and the Skoda Octavia.

The A-Class has a lower hump running down the centre of its floor than the Audi A3 and the 1 Series, so the middle rear passenger has more foot space. Mind you, getting in through the relatively small rear door apertures can be a bit of a struggle.

Seat folding and flexibility

All versions of the A-Class come with 40/20/40 split-folding rear seats, giving you greater flexibility than the 60/40 split that you get in most cheaper family hatchbacks.

That means you can carry a passenger on each of the outer rear seats, while slotting a longer item (such as a golf trolley) in between them.

Boot space

There’s nothing spectacular about the boot size in the A-Class and, while its 355 litres of space (below the parcel shelf) is enough plenty for a weekly shop or the luggage that you’ll need for a weekend away, both the A3 and 1 Series offer a bit more room.

Meanwhile, if you need maximum space from your family hatchback, check out the gargantuan Skoda Octavia.

With the split-folding rear seat backs dropped down, you get a large, flat, extended load area. The big lip at the boot entrance is a bit annoying, though, and there's no height-adjustable boot floor to mitigate this.

"At 6ft 5in I'm pleased to say I can easily find the right driving position in the A-Class. My passengers have plenty of space too, and the boot will easily swallow my weekly supermarket shopping." – Chris Haining, Sub-Editor

Buying & owning

Everyday costs, plus how reliable and safe it is

Equipment, options and extras

Entry-level Sport Executive trim gives you the basics, including 17in alloy wheels, LED headlights, rear privacy glass, climate control, heated front seats and wireless phone charging.

AMG Line Executive adds 18in wheels and sportier styling, while AMG Line Premium brings two-zone climate control, illuminated door sills and an upgraded 225W sound system.

Range-topping AMG Line Premium Plus (quite a mouthful) adds even more luxuries, including larger (19in) alloys, adaptive LED headlights and a sunroof. You'll still need to pay extra is you want adaptive cruise control – which is pretty galling in a car this expensive.

Costs, insurance groups, MPG and CO2

The majority of buyers won’t be paying cash for their Mercedes A-Class: they’ll be signing up to a PCP finance deal. If you’re planning to do that, expect to pay slightly more a month than you would for an equivalent Audi A3 or BMW 1 Series. Prices vary from month to month so make sure you check our New Car Deals pages.

If you’re a company car driver, all three engines command a similar rate of benefit in kind (BIK) tax. There's no plug-in hybrid (PHEV) version of the A-Class hatchback, but there is of the A-Class Saloon – it's called the A250e.

Anyone who pays for their own fuel will appreciate that the A200d promises to be usefully economical, officially managing more than 57mpg. Bear in mind though that equivalent diesel versions of the A3 and 1 Series are even more frugal. Even the range-topping petrol A200 is no gas-guzzler, promising up to 48mpg.

Reliability

In the 2023 What Car? Reliability Survey, the A-Class didn’t fare very well at all. It finished well down the pecking order in the family car class.

Things didn’t get much better for Mercedes as a brand, with the manufacturer placing a disappointing 24rd (out of the 32 brands). For comparison, Audi came 26th and BMW 12th.

Every A-Class comes with a three-year/unlimited mileage warranty as standard, to help give you some peace of mind. That level of coverage is par for the course.

Safety and security

Euro NCAP awarded the A-Class a five-star (out of five) safety rating in 2018, and while it scored higher marks for adult occupancy and pedestrian protection than the A3 and 1 Series, they were tested in 2020 and 2019 respectively, when the tests had become more stringent – so it’s hard to compare directly.

Even the most basic versions of the A-Class come with a host of safety features, including automatic emergency braking (AEB), lane-keeping assistance and a driver alertness monitoring system.

Blind-spot monitoring comes as standard with AMG Line Premium trim and above, while an optional Driver Assistance Pack (available only on range-topping AMG Line Premium Plus) adds more active safety assistance, such as Active Lane-change assist, Active Steering assist and Evasive Steering assist.

"Gone are the days when basic Mercedes models were Spartan inside. I was impressed to see big-car kit such as heated seats and wireless phone charging on all models." – Claire Evans, Consumer Editor
